I have a question to tax your guys' intellect. I am working on a Inspiron 8100 for a client which has a Toshiba SD C2502 DVD Drive in it. Before the machine made it to me they had put XP Pro on it which rendered the drive inoperable. Now, here is the thing, I know that this is an atapi device and it does not require drivers further than those of xp but it gives me a code 39 in the device manager and says that the driver is corrupt or missing. The drive will not show up in My Computer but does in the manager. The drive works fine before xp boots up, you can boot from it and everything. When you go into the manager and look at what drivers are installed it has four of them listed but the drive still will not function. I am reasonably certain that this is not the malfunction of the device because it works flawlessly before the windows system files boot. I have uninstalled, reinstalled, updated, rolledback and just about every other thing I can think of on this drive all with the same result. I have searched extensively on the internet and have found others having similar problems with the drive in conjunction with xp but no viable solutions. Some things indicate that this problem had something to do with the adaptec software that these machines come pre-bundled with but that software is no longer on the machine, I guess someone uninstalled it earlier. So I am kinda stumped, so if any of the brainpower out there has any good ideas please let me know, it will be worth 500 points to you. Thanks in advance.
